Abstract
We report on measurement of transmission spectra of commonly used explosives (RDX, PETN, HMX) covered by popular materials: paper, polyester and cotton in THz range (0.3-2.5 THz). Explosives were prepared as pellets, where Teflon was applied as the matrix material. We made use of Time Domain Spectroscopy and Fourier Transform Infrared Spectroscopy, which are described and results are compared. We show that characteristic features of explosives can be still identified up to 2.0 THz.
